The drawing illustrates a main track and a siding or branch track, theformer coinprist'ra'clr rail sections 1, 2 and the part '3 of the trackrail section 4. The track rail section 1 is shifta hle. The siding orbranch track' comprises an inclined shiftahle track rail sec; tion 5 andthe inclined part 6 of track rail section 4:. One end of the section 1provides a switch point 7 which when it abuts the part 6' of track railsection 4 fornisa continuation of the part 3 of section 4. One end ofthe track rail section 5 provides switch point 8 which is adapted to coact with the track rail section 2, when switch" point 8' is shifted toprovide in connection with the part 6 a siding or branch for a train topass froin'the siding or branch onto the main track or for passing fromthe main track onto thesidiag o'r'branc-h. The ties or sleepers for thetrack sections"are'indicated at 9 and certain of tlie'nr which a'redesignated 10' are of greater length than the other ties or sleepers 9.The ties or sleepers 10 project a substantial distance from the part 6of the track rail 1 and support the housing carrying a mechanism forshifting and locking a switch point or tongue and for shifting a signalto the desired position. The switch point 7 is connected to the switchpoint 8 by a coupling bar 11 which has its ends fixedly secured to theinner faces of said points. The coupling bar 11 provides for the switchpoints to shift in unison. Projecting from the coupling bar 11 is anapertured extension 12 having one end of the throw rod 13 fixedlyconnected therewith. The throw rod 13 passes below the part 6 of therail section a and below the rail section 1. A retaining rod 14 iscoupled to switch points 7 8 at the free ends thereof. Angles 15 andholdfast devices 16 are employed for fixedly securing the retaining rod141 to the switch points 7, 8. The throw rod 13 and retaining rod 1 1are disposed transversely with respect to the main track and retainingrod 1% passes below part 8 of rail section 1 and below rail section 2.The throw rod 13 and retaining rod 11 form elements of the switch standin accordance with this invention.

The switch stand includes a housing comprisin an open bottom bodyportion or cover 17 of the desired height and which seats upon a bottomforming member 18 provided with a rib 19 which is spaced from the edgeof member 17. The rib 19 is vertically disposed. The member 18 is ofrectangular contour and includes means in the form of spaced laterallyextending apertured lugs 20 for the passage of holdfast devices toanchor such member to the sleepers 10 adjacent one side of the railwaytrack. The member 18, centrally at one side thereof, that is, its innerside, is formed with a triangular shaped extension 21. The member 18centrally thereof is formed with a rectangular opening 22. The rib 19 ateach end of member 18 is cut away to provide a groove 23 which will bepresently referred to. The bottom of the body portion or cover 17 isformed with an outwardly directed flange 24: which seats upon the upperface of rib 19. The ends of the body portion or cover 17 are formed withcutouts 25 providing openings registering with the groove 23. Thepurpose of the openings provided by the cutouts and grooves will bepresently referred to. Formed integral with the upper face of member 18between its transverse median and each end is a rectangular projectionconstituting a guide. The projections are indicated at 26, 27, theformer provided with grooves 28, 29 and the latter with grooves 30, 31.The purpose of the grooves 28, 29, 30 and 31 will be presently referredto. Mounted upon the projections 26, 27, as well as being securedtherewith are retaining plates 32, 33 respectively. Holdfast devices 3 1are employed for securing the plates 32, 33 in position. The

projections 26, 27 are disposed transversely with respect to the member18 and the grooves 28, 29, 30 a d 31 are disposed transversely of theprojeceions. The grooves 28 and 30 are arranged in alignment. Thegrooves 29 and 31 are arranged in alignment. The grooves 28 and 30 arearranged in alignment with the openings provided by the cutout portions25 of the body portion or cover 17 of the housing.

Formed integral with the upper face of the member 18, at one side and atthe transverse median thereof is a grooved support 35 which inconnection with a cap member 36 pro vides a bea ring for the purpose tobe 1 resently referred to. The cap member 36 is secured to the support35 by holdtast devices The cap member is formed with a semi-circulargroove and which opposes the semi-circular groove formed at the top oithe support The groove in th cap member is designated and that in thesupport The support 35 and ap member 36 provide a bearing.

Rotatal mounted in the bearing provided by the support 35 and capmember36 is the operating shaft 11 and the latter projects outwardly andinwardly from the bearing referred to. The shaft ll is disposedtransversely oi? member 18. Collars 4-2, 13 and a l are carried by theshaft 41-1. The shaft 4.1 is provided with pair of crank arms 15, 46disposed at right angles with respect to each other. The outer end ofthe arm 15 is formed with a yoke 47 which is offset with respect to suchend. The outer end of the arm 16 is provided with a yoke 48 which isol'lsct with respect to such end. The collar 1 1 is interposed betweenthe inner c .d of the arm 15 L t M 1 i on and the support on and capmember 00. The

collar 13 is interposed between the inner end oi the arm 16 and. theinner end of the arm 15. The collar is is positioned against the innerend of arm 16, and is retai cd in position by a cotter pin 19.Journals-d in the yoke 47 of the arm is a roller 50 and journaled in theyolre 48 of the arm 4:6 is a roller 51. The purpose of the roll rs 50,51 will be presently refered to. That portion of the shaft 11 whichprojects beyond the body por tion or cover 17 of the housing is squaredand extends through the inner end 52 of an operating lever The lever isso connected to shaft 11 whereby the shaft cannot turn relatively to thelever or the lever relatively to the shaft. A securing nut is mounted onthe outer end of shaft 11 and such nut is indicated at The outer end ofthe lever carries a counterweight 5 1.

The switch stand includes a locking element mounted for shifting inopposite directions lengthwise with respect to the bottom member 18. Thelocking element comprises a bar 56 standing on its lower longitudinaledge and of rectangular contour in vertical section. The bar ispositioned in the end portion 66 inte ral with the other side 0 rooves23 28 and 30. The bar 56 in roX- imity to one end thereof is formedWlbll a notch 57 of the desired width and height and which opens at thebottom edge 58 of the bar 56. The bar 56 has as an lntegral part ther ofa depending U-shaped portion 59 prov1ding a recess Intermediate the endsof the bar 56 it is formed with a cutout havin b the ed es thereofDl'OVlClill continuations of O .1 t3 the inner edge the depei ng ti-shaped part Formed integral \Vltll the bar 56 at the top thereof is askeleton extension or link 001113115111 an inverted iE-saaoed too n7 c:n 1 f 1 1 part o1 forming a recess 52, a curw o. sine p 63 which extendsfrom one side of e part 6 side part consisting of an liiClllV 3('part'6l, a forwardly xtending downwardly inclined intermediate portion67 and a curved lower portion 68 which merges into the top of the bar 56and is oppositely curved with respect to the portion 66. The roller ispositioned to rile against the inner edge of the skeleton extension orling iil'll. also to engage in the recesses and 62 and the purposetherefor will be presently referred to.

The switch stand further includes a throwing element consisting of a bar69 shorter in length than the bar 56 and standing on its lowerlongitudinal edge. The bar 69 has a depending U-shaped strap-like part70 which provides a recess 72. The bar 69 also is formed with a cutout 73 having its edges forming continuations of the inner edge of the part70. Formed integral with the top edge of bar 69 is an upstanding link 73which gradually increases in widthfrom its lower to its upper end andhas its inner edge formed of continuations of the edges of the cutout73. he roller 51 carried by the arm 46 is adapted to ride against theinner edge of-link 7 3 and enter recess 72 and the purpose thereof willbe presently referred to. The bar 69 is mounted in the grooves 29, 31.The bar 69 is furt iermore provided with a right angularly disposedyoke-shaped lateral extension 7 1 carrying centrally of its outer end ahead ed pin or stud 75. The function of the headed pin or stud 75 willbe presently referred to.

The part 59 of the locking element and the part 7 O of the throwingelement depend through the opening 22 in member 18. The opening 22 is ofa size to provide the necessary clearance for the shifting of thelocking and throwing elements lengthwise of the bottom member 18 whensuch elements are opernected thereto, and in connection with a lever arm79 carried thereby the throwing of a switchpoint simultaneously with thesetting of the signal.

The shaft 77 extends abovethe body portion or cover 17 of the housingand depends below the sleeve 76. The lever arm 79 is arranged on shaft77 at the lower end thereof and is provided with pair of openings 80, 81at the end thereof. Fixedtothe shaft 77 and bearing against the upperend of the sleeve 76 is a crank arm 82 having 'a bifurcated outerportion 83 for straddling the headed pin or stud 75. Thelever arm 9'isadaptedto be pivotally connected, as at'84fto the throw rod 12. Onlyoneof the openings of thelev'er arm 79 is employed, depending on which wayit. is desired to throw the switch points. The lever arm 79conn'ected'by the opening and pivot 84 to the yokegshap'ed inner end 85of the throw rod 12. The upper end of the shaft 77 is provided withmeans, as indicated at 86 for detachably connecting the signal 78therewith.

The retaining-rod 1 1 in pro'XiInity to one end thereof is provided witha pair of spaced notches 87, 88 of the desired depth and width and whichopen at the top edge of rod 1 4. The notches 87, 88 associate with thebar 56 of the locking element. The notch '87 in the bar '56 associateswith the retaining rod 14:. I w

The retaining rod 14 has its outer end supported and guided in a groovedcasting 89 which is integral with and projects from one end of'thebottom member 18.

The bar 56 not only shifts lengthwise with respect to the bottom member18, but the throwing element coacts with th'e shaft 77 and lever arm 79for the purpose of throwing the switch points and shifting thesignal tothe desired position. The shifting of the signal is had simultaneouslywith the throwing or shifting of the switch points.

It will be assumedthat the switch is normal and locked and when in suchposition provides for trains to travel over theroute provided by theswitch point 7 on the track rail section 2. The retaining rod cannotslide in the casting 89 because it is prevented from so doing asone endof the bar 56 is'eitended through notch 87 of lock rod 14:. \Vhen lockrod 14 is arranged relatively to the locking element in the manner justreferred to switch points 7 and 8 are in locked position, hen the lockrod 14 is in the position just referred to the lever 53, locking elementand throwing element are in a position as shown in Figure 6. It will beassumed that the lever 53 is thrown from the position shown in Figure 6to the position shown in Figure 7. As the lever 53 moves into theposition shown in Figure 6 the crank arm 45 moves the locking element inthe direction of the arrow shown in Figure 7, the roller slips out ofcavity 62 and the roller 51 of the crank arm 46 rides along the innersurface of link 73, but up to this time the throwing element has notbeen moved. The roller 50 slips from cavity 62 and the locking elementmoves just enough to cause notch 57 to be in such position to allow theretaining rod 14 to pass through such notch. On a continuous shift oflever 53, crank arm 45 will cause roller 50 to ride clownwardly againstpart 63 of the extension or link of the locking element, without movingthe latter, but the crank arm 46 will cause roller 51 to rotate incavity 72 of the throwing element for moving the latter in the directionof the arrow shown in Figure 8. \Vhen the throwing element moves in thedirection of the arrow in Figure 8 the stud 75 on the lateral extension7 L will slide in the bifurcated end of crank arm 82 thereby turningshaft 77. When shaft 77 turns, the lever ar 79 will be carried therewithand the switch points 7, 8 will be shifted from the position shown inFigure 1 to a position whereby the switch point 8 will abut the trackrail section 2 thereby providing for a train to travel along the maintrack onto the branch or siding or from the branch or siding onto themain track. When the shaft 77 is turned it will also provide for theshifting of the signal or target 78. The switch is now reversed but notlocked, however, the retaining rod le is moved over so that its notch 88is directly in line with the end of bar 56. Now lever 53 is turneddownward until it takes the position shown in Figure 9 and the roller 51will ride against link 73, but will not shift the throwing element, butthe roller 50 is now located in the recess of cavity and moves thelocking element in the direction shown by the arrow in Figure 9, so thatnotch 57 is not located to allow movement of the retaining rod 14, thusthe switch is now locked in a reversed position.

The locking element, in connection with the crank arm l5 provides meansfor locking the switch in a position to which it has been fixed.

It is thought that the many advantages of a switch stand, in accordancewith this invention and for the purpose set forth can'be readilyunderstood, and although the preferred embodiments of the invention isas illustrated and described, yet it is to be understood that changes inthe details of construction can be had which fall within the scope ofthe invention as claimed.
